TYPOGRAPHICAL MACHINE.

Specification of Letters Patent.

Patented July 3, I91? Application and January 25, 1915. Serial No.4,100.

To all whom it may concern:

Be it known that I, Gnonen P. KINGS- BURY, a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in TypographicalMachines, of which the following is a specification, reference being hadtherein to the accompanying drawing.

My invention relates to typographical machines, such as linotypemachines of the general organization represented in U. S. LettersPatent, No. 436,532, to O. Mergenthaler, wherein circulating matricesare released from a magazine in the order in "which their characters areto appear in print and then assembled in line, the composed linetransferred to the face of a mold, the mold filled with molten metal toform a slug or linotype against the matrices which produce the typecharacters thereon, and the matrices thereafter returned throughdistributing mechanism to the magazine from which they started.

Ordinarily, these machines are equipped with a so-calledfont-distinguisher which is located in the clistributer box just inadvance of the distributing mechanism proper and serves to preventdelivery thereto of matrices of improper font. In the use of suchdistinguis'her, however, the presence in the composed line of such amatrix is not detected until after the casting operation has beeneffected, with the result that the slug bears a type character of Wrongfont and consequently must be discarded and a new slug cast in placethereof. This is not only annoying but occasions an unnecessary waste oftime. In addition, in order to remove the ofi'ending matrix, theoperator is compelled to leave his seat at the keyboard, and pass to therear of the machine, where he will be within reach of the distributerbox.

To overcome these various objections, I propose to locate thefont-distinguisher at some point in advance of the casting mechanism, sothat the presence of a foreign matrix may be detected before the castingtakes place. Preferably, I mount the distinguisher on the assembler,wherein the line is composed, so that when the improper matrix isdetected, it may be readily removed and without requiring the operatorto leave his Seat at the keyboard I also p p to ploy an arrangement ofsome suitable character which will direct the attention of the operatorto the presence of the improper matrix when it is detected. In one ofthe forms herein shown, I have provided looking means which, when amatrix of wrong font is present in the composed line, arrests the upwardmovement of the assembler and thus prevents the delivery of the line tothe transfer devices which carry it forward for casting. In anotherform, I have provided an alarm which will be operated under similarconditions, as the elevator is raised. Other objects and the means forattaining them will later be described and finally pointed out in theclaims.

In the accompanying drawings, I have shown my invention only inpreferred form and by way of example, and as applied to a linotypemachine, but obviously many changes and variations may be made therein,and in its mode of application, without de parture from its spirit.Generally speaking, I desire it to be understood that I do not limitmyself to any specific form or embodiment, except in so far as suchlimitations are specified in the claims.

Referring to the drawings:

Fig. 8 illustrates a modification.

I have shown herein only such parts of a linotype machine as areconcerned with my present invention. The other parts may be of the usualconstruction as embodied in the commercial linotype machine or asillustrated in the patent before mentioned.

The matrices X as they are released from their magazine pass onto thetraveling belt A, which delivers them to the assembler B wherein theyare composed side by side in line. The assembler is thereafter raisedand leaf spring F on the elevator,

delivers the composed line to the carriage C, which transfers it endwisethrough the intermediate channel D for presentation to the mold, all aswell understood in the art. The assembler B is provided as usual withtwo movable blades 1) and b, the latter arranged at the receiving end inposition to arrest the descending matrices at their higher level, atwhich they are supported by the other blade b. The assembler is alsoprovided with the customary swinging gate B, whereby access may be hadto the line when desired.

According to my present invention, I provide the assembler B with afont-distinguisher which may cooperate with the matrices during or aftercomposition and detect the presence of one of improper form or font. Inthe present instance, the distinguisher is in the form of a plate Eextending throughout the length of the assembler and attached by meansof a screw E to an overlying bar F, which latter is carried at itsopposite ends by a pair of arms F pivoted, as at F, to the side membersof the gate B. The arm F at the right has a downward extension Fcarrying at its lower end a roller F which tracks upon an inclinedsurface G formed on a bracket G attached to the framework of themachine. The other arm F of the bar F is provided with a roller Farranged in engagement with a the spring tending normally to move thebar F and the attached plate E inwardly toward the matrix line. However,the roller F on the downward extension F will engage the inclinedsurface G, when the assembler is in its lowermost or normal position andhold the plate E away from the matrix line, as indicated in Fig. 2. Theeffect of this arrangement is that the plate E will be moved toward andfrom the matrix line as the assembler is raised and lowered,respectively.

The matrices X of a given font are each provided in one of theirvertical edges with two notches m, which notches are adapted to registerhorizontally when the matrices are composed in line. The purpose of theduplicate notches is to allow the matrices to be assembled at twodifferent levels in the line, in which event the lower notches of thematrices at the upper level will register with the upper notches of thematrices at the lpwer level, as shown for example in Fig.

It is pointed out that the vertical position of the plate E is such thatwhen moved inwardly by the rocking of the bar F itwill enter the alincdnotches w of the matrices: It follows, therefore, that if there bepresent in the composed line a matrix without such notch, or one whosenotch does not register with those ofthe other matrices (Fig. 3), theinward movement of the plate E will be arrested or prevented and thepresence of the offending matrix thus detected.

I also provide means to arrest the upward movement of the assemblerwhenthe plate E is held against inward movement by an improper matrix.To this end, the extension F is formed with a laterally projecting lug Fwhich is adapted to cooperate with a shoulder G on the bracket G, thelug F and shoulder G being so located as to stand in vertical alinementwhen the plate E is in its normal position away from the matrix line. Asa result, if the plate E is maintained in this position, by reason ofthe presence of a foreign matrix, these parts will engage and arrest theassembler when it is attempted to raise it for the transfer of the line,as shown in Fig. 5. If, however, the matrices of the composed line areof the same font and in proper order, all their notches will aline andallow the plate E to be moved inwardly thereinto. In this event, the InF 5 will be moved out of register with t e shoulder G so as to clear itand allow the assembler to be raised in the regular way, (Fig. 4).

he general operation of the parts will be clear from the foregoingdescription, and it suffices to say at this point that the initialupward movement of the assembler will automatically effectthe movementof the plate E inwardly toward the composed line to detect a foreignmatrix therein, and that the further movement of the assembler willdepend upon the presence or absence of such a matrix. In this manner,the operator is advised as to the constitution of the line, and mayproceed to correct it, if necessary.

In Fig. 8 I have shown, as an alternative construction, an alarm toindicate the presence of the improper matrix. In this figure, the lug Fon the extension F is adapted to engage a spring-pressed arm H carryingat its outer end a striker H for a bell H According to this arrangement,when the plate E is held against inward movement by an ofiending matrix,the raising of the assembler causes the lug F to engage the arm H andmove the striker H to active position, it being released when the lugpasses the arm in the continued movement of the as sembler. The strikerthen sounds the alarm and notifies the operator.

It will be understood that different fonts of matrices Will be formedwith diflerently located notches. I therefore mount the plate E so thatit may be adjusted vertically to different positions to correspond tothe location of the notches in the matrices of one font or another. Inthis connection, it will be noted that the screw E, previously referredto, passes upwardly through an opening in the bar F and is provided atits outer end with an adjustable nut E, which bears upon the upper faceof the bar, and, as shown in Fig. 1, that the plate E is provided at itsopposite ends with a pair of guiding studs E fitting in sockets in thebar F, the studs being surrounded by spiral'springs E which tendnormally to urge the plate downward. It will be seen, therefore, that byturning the nut E in one direction or the other, the plate E may beraised or lowered to the desired position. An indicator I may beemployed to assist the operator in effecting the proper adjustment ofthe plate.

In order that the spacers Y will not interfere with the detectingmovement of the plate E, I form each of them with a cut or notch 3 of-adepth corresponding to that of the notches in the matrices and of anextent snfiicient to accommodate the plate in any of its difi'erentvertical positions.

As before pointed out, the bar F which carries the distinguisher plate Eis connected to the swinging gate B. As a result of this arrangement,the gate and its connected parts are free to be swung downwardly in theusual Way to give access to the matrix line, as shown for example indotted lines in Fig. 6. The customary spring F presses against theroller F 8 on one of the arms of the plate F and serves to hold the gatein its proper position,.just as heretofore.

As previously stated, I have shown my invention merely in preferred formand by way of example, and it will be obvious that many modificationsand alterations therein will suggest themselves to those skilled in theart, and still be comprised within its scope.
